The Whirlpool W10853393 Range Switch-Rocker is an essential tool used to regulate your range's cooktop. It functions as an interface, converting your control panel's knob or rocker actions into electrical impulses. These signals control the power given to the range's heating components. In layman's terms, whether you turn the knob to simmer, bake, broil, or high heat, the switch perceives the setting and transmits appropriate electrical instructions to reach the specified cooking temperature. This switch, located on the range's control panel, is essential for a wide range of cooking tasks. A malfunctioning switch can result in problems such as a fully dead range, inoperable cooktops, or the inability to modify heat settings. Replacing a broken switch with the W10853393 restores your range's functionality.
